Fan Query

[TatamiMatt]

Hi all, i fell in with some fans from work that were going to be otherwise dumped, though im not sure how to use them or what for as they are 48V fans, any info/help/tips for these?

well do you have a 48v power supply

I do not, but wondering if there are any other use cases in which these can be wired to, not strictly computer related, i have a soldering kit and would just be a fun project to see what these fans can do

Well, anything that requires/related to cooling, air intake, exhausting, circulation

You still need to provide 48v to it, at the very least if you want them at their max capability.

 

And some kind of controller if you want to control their speed.

This can be either just a dumb potentiometer if they are running in DC mode, or PWM controller if they are running in PWM mode.

theres an controller just need a psu

I did try plugging the fans into a 12V power supply, one smoked and smelled like gunpowder, another 2 did nothing, not sure what went wrong with the first, but i think even 12V is too little to move them

Yes, because you need at least 40V according to the datasheet.

I'd sell it... ~40W for a single fan. Heck my ceiling fans are 50-60W.

Shorted maybe

But but, jet engine sound

Yeah, i got curious and pulled it apart, couldnt see anything super obvious, but possibly a blown resistor/capacitor

I have about 10, so could easily sell a handful, they go for quite a bit from what i can see, but i do really want to see how they run, mainly because jet engine sound go brr to be honest

Well the only way to do that is to provide 48v

So either you buy a 48v power supply, or steal one (just kidding about the stealing, don't)

Could you get a bench power supply?
